Genotype × Environment interaction (GEI) effects are of special interest to identify stable genotypes plant breeders. The present experiment was conducted in three growing seasons viz., Kharif 2019, springsummer 2020, and summer 2021 at Research Farm, C.S. Azad University of Agriculture and Technology, Kanpur, to assess the stability of 48 F1 hybrids along with 19 homozygous mung bean parents for seed yield per plant. AMMI1 biplot for seed yield per plant, the hybrids viz., PDM139 × KM2355, IPM147 × KM2355, KM2241 × MH1142 and PM1125 × MH1142, similarly IPM 147-1, KM2241 and KM2255 parents had IPCA1 score close to zero with high main effects indicating that these hybrids were less influenced by environments and high yielders. PDM139 × PM1126, IPM147 × PM1126, KM2241 × KM2355 and KM2352 × MH1142, and parents KM2328, SML1811, KM2360, and IPM147, were found to be high yielders with high interaction with the environment. Among environments, Kharif and Summer seasons are highly interacting environments. Finally, the hybrids viz PM1125 × MH1142 and PDM139 × KM2355 were found less interacting hybrids with high seed yield per plant. These hybrids may be recommended and used in other crop improvement programs for all three growing seasons of mung bean.

Highlights

• Mungbean is an important grain legume crop widely cultivated in all growing seasons.
• Identification of stable and high-yielding hybrids through AMMI analysis, to enhance the production and productivity of green gram crop.
